My Tire Pressure Gauge and TPMS are 4 PSI off whether tires are hot or cold. I recently purchased a new tire gauge and it falls in between the 2. Which one should I go by?

Can you calibrate the TPMS somehow?

i dont think it is possible to calibrate tpms... maybe the tpg is what is off... not your tpms

I'm using a digital tire pressure gauge with spec accuracy to within 0.5 PSI.

When checked against the TPMS displays for my set of summer and also my set of winter wheels, the numbers are off by not more than 1 PSI.

My TPMS is about 1-2 psi off compared to when I check the tires with a gauge. Close enough for the girl I married.

1 or 2 PSI is not going to cause that much problem between your gauge and the TPMS

If you ar a "bit" anal/OCD like me, I filled mine until my display matched (needed an extra .5 in the left rear)

Pack, I think the answer is "good enough". 1-2 pounds should not make that much of a difference.
